Mine Electronic Air Velocity MeterCFJD25B
Product Features
CFJD25（BSeries (Model) Coal Mine Mechanical-Electronic Wind Speed Meters are the new generation of intelligent digital wind speed and air volume detection instruments. Mainly used for measuring instantaneous wind speed, average wind speed, and average air volume. This anemometer is a high-precision, wide-range precision wind speed meter, integrating high-speed, medium-speed, and low-speed into one. It employs an imported high-performance, new-type microprocessor internally, which automatically corrects the non-linearities of the three wind speed ranges. The corrected data is more accurate.
Primary Functions
》Measurable: Instantaneous wind speed, timed average wind speed, timed average air volume.
Measurement Mode: Average wind speed measurement, which can be conducted using either the sweeping line method or the fixed grid method.
》Timer can be set to any second;》Equipped with an automatic shutdown feature;》Powered by a rechargeable lithium-ion battery
Multiple display functions: Instantaneous wind speed displaym/sValue
Average wind speed displaym/sValue, m/minValue
Average Airflow Displayedm³/sValue, m³/minValue;
Low-voltage display function available.
The screen displays the countdown timer in seconds during measurement.
Main Applications and Usage Scope
This anemometer is primarily used for measuring wind speed and volume in underground coal mines, suitable for use in environments with explosive gases and coal dust. It is also applicable in other flammable and explosive situations. Its range of applications includes various aspects of wind speed and volume measurement in industries, agriculture, meteorology, construction, mining, tunnels, HVAC systems, fans, pipelines, and ventilation in numerous settings.
